The quantum capacity is the maximum rate at which quantum information can be communicated/corrected over many independent uses of a noisy quantum channel. In other words, the concept of the quantum capacity establishes the quantum rate limit for which reliable (i.e., with a vanishing error rate) quantum communication/correction is asymptotically possible. The definition of the quantum capacity, often referred to as the Lloyd-Shor-Devetak (LSD) capacity, is given by the following theorem [1]}, [2]}.
